Definitions
- Cutting and transport devices for material webs are known. Most of them are used in winding devices for such webs. However, it is also conceivable that such cutting and transporting devices are used to cut material webs into shorter track sections and that these shorter track sections are subsequently further processed or further stored in a manner other than by winding.
- the further processing for example, in the printing and subsequent separation exist; the further storage could for example consist of stacking shorter sections of track.
- winding devices are usually transported by a plurality of transport rollers. They are fed in this way winding points. At these winding locations winding tubes are wrapped with the transport paths until the cores reach a desired diameter and so store a desired amount of film. More modern winding devices have the option of exchanging fully wound winding sleeves for empty winding sleeves during operation. For this purpose, the moving web must be cut in the winding device. The web start of the cut web must then be determined on a new winding tube. For this purpose, a variety of methods are known. So can be wrapped with the help of glue or tape; However, it is also known to determine the free beginning of the web on such a winding tube with the help of vacuum or even electrostatic charge.
- Such stretching methods are known to the person skilled in the art. They play a role in blown film extrusion and in the inflation of the film bubble. In the flat film extrusion can be stretched for example by a higher speed of the take-off rolls. Often, however, there are particularly complicated stretching methods in which film is cooled or heated to a certain film temperature and then a stretching process takes place. Defined conditions under which to stretch are of particular importance. In all materials in which a high stability in the transport direction of the film is achieved, it comes to the described Auffaerefen when cutting the film. This fusing lowers the quality of the film, is a hindrance to the Anwickel perspectives and thus also reduces the quality of the resulting film wrap.
- the object of the present invention is to propose a cutting device in which a better, cleaner cutting result is achieved.
- the object is achieved in that a web reinforcement device is provided, which reinforces the material web with reinforcing material at the points which are later cut with the cutting tool.
- a control device is provided.
- Such a control device may be possible by programming to tune the application of the reinforcing material to the moving material web and the cutting process in such a way that the knife or the cutting tool cuts through the material web precisely at the point at which the reinforcing material is applied.
- the control device will for this purpose record or transmit the position of the reinforcing material on the path of the transport direction or know the point in time at which the reinforcing material is applied.
- a suitably programmed control device can control the knife or cutting tool so that the web is severed at the reinforced site.
- the control device must also know the cutting point, ie the point within the machine at which the cutting blade becomes active.
- various materials come into consideration. These include, among others, viscose materials such as extrudate and adhesive or hot melt and strips of material.
- the reinforcing material is preferably applied orthogonal to the material direction. Material strips with self-adhesive layers are preferred.
- an application roller When applying reinforcing material to the moving transport path, it is advisable to provide an application roller.
- This application roller can be supplied, for example, the strip of material. Then the application roller can be led to the moving web and roll off with this web. During this rolling movement, the application roller can preferably transfer the material strip with its adhesive surface to the moving web.
- the device features described are particularly advantageous in winding devices of all kinds integrable. These include both contact and turret winder. Modern winder of these types have so-called transport cutting rolls, in which the material web transported on the roll is cut by a knife, which passes through the roll peripheral surface during the cutting movement. In high-end Wicklem the movement of the transport cutting roller is reversible and in both directions of movement of this roller Anwickelvor réelle be feasible. These winder are called "reversing winder”.
- FIG. 1 Sketch of a inventively equipped contact winder; Fig. 2 The same sketch, with a new cutting and Anwickelvorgang imminent.
- Figures 1 and 2 show a sketch of a contact winding device, wherein only the rollers and Anwickelhülsen involved in the web transport, an old material winding and the web were shown themselves. For reasons of clarity, further components of the winding device are not shown here. These include the rollers, the machine frame and the actuators required for the movement. These devices are known to the person skilled in the art and are described, for example, in the applications DE 102 02 462, DE 102 02 687, DE 102 03 149, DE 102 02 463, DE 103 21 642, DE 103 21 599, DE 103 21 600 and DE 103 21 778 called.
- the material web in FIG. 1 and in FIG. 2, after it leaves the transport cutting roller 6, is guided onto the almost full film roll 8 and further wound up here.
- the application roller 10 which is movable from the position P1 to the position P2 along the arrow 12.
- the application roller 10 In the position P1, the application roller 10 has no contact with the material web 1 and can therefore be at rest, wherein a strip of material 13 in the axial direction of this roller can be supplied to the same.
- This strip of material 13 is the same length as the material web 1 is wide.
- the application roller 10 rolls off with the material web 1 and transfers the material strip 13 to the location of the material web 1 provided for this purpose.
- the use of self-adhesive material strips is advantageous.
- a roller is often used as the application roller, which is provided with air outlet and -intrittsö réelleen.
- the winding device shown also has a control device, which is also not shown.
- the adhesive strip is fed onto the roller in the axial direction of the roller, air often comes out of the exit holes of the roller . blown. In this way, the strip can slide on an air cushion on the roller. If the strip has reached its application position on the application roller 10, it is expedient to fix this application strip there. This can be done, for example, by applying a vacuum to the roller in its interior, so that the strip is sucked in through the air outlet or entry holes.
- the application roller 10 Before the application process, it is often expedient to set the application roller 10 in motion before it comes into contact with the material web 1. In this case, a circumferential speed of the application roller 10 can be set which corresponds to the web speed of the web 1.
- the machine controller knows the appropriate application location on the web 1 in time, it can control the rotation of the application roller so that the application strip is fed from the application roller at the correct point on the web. It is expedient if the roller also touches the material web 1 at the time which is suitable for the application.
- the winding device shown also has a control device, which is also not shown.
- This control device is known at which point the material strip is applied to the web.
- This point of the material web 1 is provided by the control device as an interface.
- the control device is the path between the application point in the nip between the application roller 10 and the interface in the new Anwickelhülse 9 known.
- the control device can measure the material speed of the material web 1 between these two locations. From these two variables, the control device calculates the transit time and accordingly coordinates the cutting movement of the blade 7 with the application process, which is carried out by the application roller 10.
- the applied strip of material is already on its way to the location of the cutting process.
- the strip of material 13 is located between the transport roller 3 and the transport roller 4.
- the material strip 13 is already above the blade 7 on the peripheral surface of the contact roller 6.
